but in this case the polarity is wrong
NO, it is NOT, the polarity is RIGHT (/RESET for both devices) one PNP transistor and a base resistor or a diode Fooling around with "one PNP transistor and a base resistor or a diode" in a reset circuit will, most likely make it worthless since the tresholds would get higher. The dedicated supervisor circuits start off holding reset waaaay earlier than you can achieve with homebrew solutions. Erik |
